Routine RouterOS Update Process: Step-by-Step

RouterOS Update Routine: Keeping Firmware Current

Updating RouterOS regularly is not optional — it is part of responsible network management. This post covers how to build a repeatable, safe update process that fits into your operational workflow.

Monthly Firmware Review Checklist

1. Check current version: /system resource print
2. Check latest stable: visit mikrotik.com/download and check your hardware's channel
3. Read the changelog: mikrotik.com/changelog — look for security fixes relevant to your setup
4. Assess risk: major version? patch? check community forums for reports of issues

Update Channels

RouterOS has three release channels:

• Stable: thoroughly tested, recommended for production
• Long-term (LTS): older version with extended support, maximum stability
• Testing (Candidate): early access to new features — avoid in production

For most environments, stay on Stable.

Pre-Update Steps

# 1. Take a backup
/system backup save name=("pre-upgrade-" . [:tostr [/system clock get date]])

# 2. Note your current version
/system resource print

# 3. Check disk space for download
/disk print
/file print

Update via CLI

/system package update check-for-updates channel=stable
/system package update download

Wait for download to complete, then install (causes reboot):

/system package update install

Update Multiple Routers Efficiently

For managing many devices, use The Dude (MikroTik's free network monitoring tool) or a simple bash loop with SSH:

for ip in 192.168.1.1 192.168.2.1 192.168.3.1; do
  ssh admin@$ip "/system package update download; /system package update install"
done

Or use Ansible with the community.routeros collection for proper change management.

Post-Update Verification

After reboot:

/system resource print  # confirm new version
/interface print         # all interfaces still up?
/ip route print         # routing table intact?
/ip firewall filter print count-only  # rule count matches?

Compare with pre-upgrade /export if anything seems different.

Handling Failed Updates

If the router doesn't come back after an update:

1. Console access (physical serial or Winbox over another path)
2. Check for package compatibility errors in the log
3. Use NetInstall as a last resort to reinstall clean RouterOS

Scheduling Automatic Updates (Use With Caution)

RouterOS can check and download updates automatically, but don't enable automatic install without a maintenance window plan:

/system package update set channel=stable
# Check-only automation (don't auto-install in production):
/system scheduler add name=check-updates interval=1w on-event="/system package update check-for-updates"

Review and manually install during planned windows to avoid surprise reboots during business hours.

Keeping firmware current is boring until it isn't — a patched CVE prevented is far better than an emergency incident response after a compromise.
